Kua tāruatia ki te papatopenga
-56x=8-20
Whakareatia ngā taha e rua o te whārite ki te 4.
-56x=-12
Tangohia te 20 i te 8, ka -12.
x=\frac{-12}{-56}
Whakawehea ngā taha e rua ki te -56.
x=\frac{3}{14}
Whakahekea te hautanga \frac{-12}{-56} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -4.
